N2 - Sol-gel and Erbium-doped sol-gel glasses are fabricated through polymeric sol-gel technique. This work mainly demonstrates an effective strategy to improve the radiation resistance through glass fictive temperature reduction. The mechanisms are experimentally through UV-Vis- IR spectroscopic techniques. γ-irradiation leads to decrease of the frequency of Si-O-Si band that is likely due to an increase of the fictive temperature associated to an average reduction of bonding angle. Furthermore, we found that that ?-radiation "hardness" is higher in Er3+ doped sol-gel silica than that of standard synthetic or natural silica glasses.
